无效移动条件，基于Python文本的游戏

Question

我需要一个基于文本的python游戏的帮助，我已经完成了大部分工作，我可以在所有3个房间之间移动，顶部有“大厅”，然后往南走“卧室”往东走“地窖”我可以往回走，所以往西走“卧室”向北走，最后回到大厅。

问题是，如果我在大厅里输入东，它会跳到地窖，而不是说无效移动，那里有一面墙。我想做的是

显示玩家当前所在房间的输出。决策分支告诉游戏如何处理不同的命令。命令可以是在房间之间移动（如向北、向南、向东或向西）或退出。如果玩家输入了有效的“移动”命令，游戏应该使用字典将他们移动到新的房间。如果玩家进入“出口”，游戏应该将他们的房间设置为一个叫做“出口”的房间。如果玩家输入无效命令，游戏应该向玩家输出错误消息（输入验证）。一种在玩家进入“退出”房间后结束游戏循环的方法

这是目前为止我写的代码

rooms = {
    'Great Hall': {'South': 'Bedroom'},
    'Bedroom': {'North': 'Great Hall', 'East': 'Cellar'},
    'Cellar': {'West': 'Bedroom'}
}


def player_stat():
    print("-" * 20)
    print('You are in the {}'.format(currentRoom))
    print("-" * 20)


currentRoom = 'Great Hall'
player_move = ''

while currentRoom != 'Exit':
    player_stat()
    player_move = input('Enter your move:\n')
    if player_move in ['Exit', 'exit']:
        currentRoom = 'Exit'
        print('Play again soon')
    elif player_move in ['South', "south"]:
        currentRoom = 'Bedroom'
    elif player_move in ['North', "north"]:
        currentRoom = 'Great Hall'
        print("You made it back to the Great Hall")
    elif player_move in ['East', 'east']:
        currentRoom = 'Cellar'
        print('YOU MADE IT TO THE CELLAR, try to go back to the Great Hall')
    elif player_move in ['West', "west"]:
        currentRoom = 'Bedroom'
print("You made it back to the Bedroom")

请帮帮我

Answer 1

我修改了你的代码来利用字典。它涉及嵌套的条件语句。

rooms = {
    'Great Hall': {'South': 'Bedroom'},
    'Bedroom': {'North': 'Great Hall', 'East': 'Cellar'},
    'Cellar': {'West': 'Bedroom'}
}


def player_stat():
    print("-" * 20)
    print('You are in the {}'.format(currentRoom))
    print("-" * 20)


currentRoom = 'Great Hall'
player_move = ''

while currentRoom != 'Exit':
    player_stat()
    player_move = input('Enter your move:\n').title()
    if player_move == 'Exit':
        currentRoom = 'Exit'
    else:
        if player_move in rooms[currentRoom]:
            currentRoom = rooms[currentRoom][player_move]
            if currentRoom == 'Great Hall':
                print("You made it back to the Great Hall")
            elif currentRoom == 'Cellar':
                print('YOU MADE IT TO THE CELLAR, try to go back to the Great Hall')
        else:
            print("That is not a valid move, try again.")

print('Play again soon')

Answer 2

rooms = {
    'Great Hall': {'south': 'Bedroom'},
    'Bedroom': {'north': 'Great Hall', 'east': 'Cellar'},
    'Cellar': {'west': 'Bedroom'}
}


def player_stat():
    print("-" * 20)
    print('You are in the {}'.format(currentRoom))
    print("-" * 20)


currentRoom = 'Great Hall'
player_move = ''

while currentRoom != 'Exit':
    player_stat()
    player_move = input('Enter your move:\n').lower()
    if player_move in ['Exit', 'exit']:
        currentRoom = 'Exit'
        print('Play again soon')
        continue

    try:
        currentRoom = rooms[currentRoom][player_move]
    except Exception:
        print("invalid move")
        continue


    if currentRoom == 'Great Hall':
        print("You made it back to the Great Hall")
    elif currentRoom == 'Cellar':
        print('YOU MADE IT TO THE CELLAR, try to go back to the Great Hall')

print("You made it back to the Bedroom")
